Can I Use Any SBC or My Existing CUCM or AURA SM for Direct Routing?
Currently Microsoft Support only Audiocodes and Sonus / Ribbon SBCs for Direct Routing. This is not to say you may get some success with others, but they’re not officially supported. Microsoft are implementing media bypass support and this requires the SBC to support ICE Lite. Currently only Audiocodes and Ribbon have this capability.
